White jade snail is a kind of edible snail, with huge individual, white flesh, tender and beautiful, and high economic benefit. It is quite competitive in the international market.

(l) Advantages of field cultivation

First, with fast growth, wild breeding can meet the requirements of snails on the three elements of temperature, humidity, and feed. Therefore, the growth and development are fast, and the growth rate is higher than the wooden box culture. The second is white meat with good quality. Third, the pattern of shells is clear and bright, and it is very suitable for making shell carving crafts. The fourth is the provincial labor, provincial feed, many products, and high income.

(2) Wild Breeding Conditions

1 White jade snails will freeze to death below 5°C. Therefore, the area where the average winter temperature is above 5°C can be used as the boundary for wild aquaculture. Most of the Yangtze River in China can carry out wild culture.

2 To find a good market, breeding snails must first implement a good market, so as to avoid the production of products and cause economic losses.

3 There are strict measures and equipment to prevent escape of white snails.

4 It is necessary to maintain the ecological environment of wild aquaculture sites without human and other biological damage.

(3) Breeding technology

1 The choice of site should be lee, shady, wet, well-drained, long weeds or shrubs, jungle hills, hillsides, hills, wilderness areas, and idle areas behind the house front can be used as a breeding ground.

(2) Construction of anti-abandon facilities (a) Excavation of ring ditch. Around the breeding site, dig a ditch, which is generally 10 cm wide and 5 cm deep. Conditional ditch can store shallow water. This ring field ditch prevents both snails from fleeing, and it can also be used to store water in the yard. (b) Planting onions, garlic, leeks, onions, etc. around the site as the isolation zone. Because the above plants can evaporate spicy odors, they have a certain repellent effect on snails. (C) Using wire mesh or plastic nets to make inward turning angles and become "┐"-shaped fences. When the snail crawls to the top, it will fall into the farm due to inconvenience of turning and the center of gravity. (d) Using the characteristics of the snail's physiological response to high alkaline avoidance, around the farm, bricks are used to make a circle about 1 meter high, and a high-alkalinity three-concrete cement with a thickness of about 1 cm is applied to the inner wall of the wall. pH value For 11.5, the anti-escape effect is very good.

3 timely placement of young snails when the temperature began to stabilize at 20 °C when the placement of young snails, in Nanjing in May 10 -20 days, juvenile snail age to be neat, with 2-3 months of age, weight 5-10 g for It is recommended that stocking density be 100-200/m2.

4 Strengthen Management Every night and early morning, especially after the rain, white jade snails are in the peak of their activities. In time, they can be checked back to escape the snails in time.

5 Do harm to natural enemies such as rats, frogs, snakes, birds, turtles, crickets, and ants.

6 When products are sold in time in early September, when the snails weigh more than 30-50 grams, they must be sold in time to prevent loss caused by disaster weather.
